In the first episode of a series exploring the history of American art, Andrew Graham-Dixon embarks on an epic journey from east to west, following in the footsteps of the pioneers who built the foundations of modern America. During his journey, he travels to Massachusetts to see the earliest portraits in America depicting the Puritan settlers and visits Pennsylvania to uncover the dark truth behind Benjamin West's most famous painting, the spectacular Treaty of Penn with the Indians. In Philadelphia, he turns the pages of one of the world's most expensive books - John James Audubon's exquisite Birds of America, and explores the wilderness that inspired America's greatest landscape painter, Thomas Cole. He also uncovers the paradox at the heart of America: that progress and innovation have come at a tragic price, the destruction of the unique cultural heritage of Native Americans by European settlers. Andrew's journey takes us to the end of the 19th century and the announcement that the era of westward expansion was officially over.

In the second part of his fascinating journey exploring American art, Andrew Graham-Dixon gets under the skin of the modern American metropolis. Starting his journey at the foot of the Statue of Liberty, which he describes as a pioneering early skyscraper, Andrew discovers how the ambitions of visionary artists and architects helped America remove itself from the shadow of Europe and become the most advanced civilisation on earth. Andrew travels to downtown Manhattan to explore the grimy world of early 20th century painters John Sloan and George Bellows, and visits Stockbridge in Massachusetts to find out how the world of Norman Rockwell is not as sentimental as it first seems. In Chicago, he explores the visionary mind of architect Louis Sullivan and travels to the decaying outskirts of the city to see the underside of the American dream. He uncovers the impact the Great Depression had on artists such as Edward Hopper and Arshile Gorky, and finds out how this struggle inspired America's first internationally-acclaimed art movement - Abstract Expressionism. He pays a pilgrimage to Jackson Pollock's perfectly-preserved studio in Long Island to discover the secrets of his unique drip technique, before flying across America to take in one of modern art's most moving experiences, Mark Rothko's chapel in Houston, Texas.

In the final part of his United States odyssey, Andrew Graham-Dixon feels the pulse of contemporary America. Beginning in Levittown - the first mass-produced suburb - Andrew uncovers the dark side of post-war consumerism and the role artists have played in challenging the status quo. He visits New York's Metropolitan Museum to see the most subversive artwork of 1950s America, Jasper Johns's White Flag. Pop art defined the 1960s and Andy Warhol was its greatest artist. Andrew examines Warhol's soup can paintings, meets his former lover Billy Name and interviews one of the last great surviving pop artists, James Rosenquist. He travels west down the open road, exploring its art, arriving in Los Angeles, an artificial dream world that has inspired the graphic style of Ed Ruscha and the city's own unique contribution to 20th century design - Googie architecture. Back east, Andrew visits the home of one of his favourite 20th century artists, the late Philip Guston, and gets a private view of his work. He drops into the studio of Jeff Koons to learn how the enfant terrible of contemporary art continues to challenge the boundaries of American taste. Finally, he explores the impact 9/11 has had on America and how a new generation of artists, such as Matthew Day Jackson, have made sense of this tragic event.
